1 Claim.

My present invention, in its broad aspect, has to do with improvementsin transmission devices for increasing the effective power of any motor,or other prime mover coupled with it, and the details of constructioninclude reciprocating rack bars having pivoted toothed levers engaging atoothed driven wheel after the manner of an escapement to advance thedriven wheel which is of relatively large diameter with a step-by-stepmotion caused by reciprocation of the rack bars by the prime moverthrough a reciprocating arm and a link connection with the bars toadvance one bar while the other is retracted. The driven wheel iscarried on a driven shaft on which is mounted a toothed wheel of lesserdiameter than the driven wheel and meshing with a small gear on a flywheel shaft from which the power is taken. Upper and lower gears supportand steady the rack bars, and the transmission is mounted on asubstantial foundation and base. My transmission is simple, sturdy, easyto install and operate, may be" used with any source of power totransmit power for any purpose, and has no fragile or intricate partslikely to get out of order or to become deranged or broken.

Other and equally important objects and advantages of my invention willbe apparent from the following description and drawings, and it is Ipointed out that changes in form, size, shape, ma-

terials, and construction and arrangement of parts are permissible andwithin the purview of my broad inventive concept, and the scope of theappended claim.

In the drawings, wherein I have illustrated a preferred form of myinvention:

Figure 1 is a top plan view, and

Figure 2 is a side elevation.

In the drawings, wherein like characters of reference are used todesignate like or similar parts throughout the several views:

The numeral I designates a base, having a platform 2, end supports 3 and4, and mounted on spaced foundation piers 5 of masonry structure.Mountedon the end support 4 is a housing Bfcarrying a slide valve 1 onsupporting rails 8 for controlling the operation of a reciprocatingenglue. The slide valve 1 has an arm 9 with an elongated slot H), In theslot is received a pin l l on the rod l2 of apiston I3 in a cylinder Mwhich may be an air or steam type of prime mover which may be coupledwith my transmission. Reciprocation of the piston moves the valvethrough the arm to contact introduction of whatever power element isused. Also coupled with the pin I l is a rocking lever l5 centrallypivoted, as

at IS, on the plate ll. Also coupled with the pin II is the curved endof a horizontally disposed rack bar l8, and coupled with the oppositeend of the rocking lever I5 is the oppositely curved end of anotherhorizontal rack bar l9 parallel with and spaced from the bar l8. A pairof vertical spaced supports 26 are mounted on the plate I! and anotherpair of spaced supports carries upper and lower gears 22 and 23 betweenwhich the rack bars reciprocate and are supported and steadied. Mountedin journals 24 on the platform 2 is a shaft 25 which carries ratchettoothed wheel 26 of relatively large diameter which is on each side of acurved arm 21 and 28 on each of the rack bars l8 and I9 so that as thesebars are alternately reciprocated the wheel is rotated by the arms 21and 28 with a rapid step-by-step movement, one rack bar is positioned oneach side of the wheel, as shown in Figure 1. Also mounted on each sideof the Wheel on the shaft 25 are small auxiliary steadying ratchetwheels 29 engaged by dogs 30' on the under sides of the rack bars. Keyedto the shaft 25 is a large spoked gear wheel 3| which meshes with gear32 on shaft 33 journaled in bearings 34 on the platform 2 on which isthe balance wheel 35 which is the drive element of my transmission.

From the foregoing it is believed that the operation and advantages ofmy transmission will be apparent, but it is again emphasized thatinterpretation of the scope of my invention should only be conclusivewhen made in the light of the subjoined claim.

I claim:

A transmission device, comprising a driving shaft. a ratchet wheelsecured thereto, a driving spur gear secured to said shaft and spacedaxially from said ratchet wheel, a reciprocating bar on each side ofsaid ratchet wheel, means supporting the bars for reciprocatingmovement, a pivotally mounted lever, a pin and slot means connectingeach end of the lever with one of said bars'where- I by oscillatorymovement of said lever causes reciprocation of the bars in directionsopposite to each other, a prime mover for oscillating said lever, a pairof pawl members offset from said bars, said pawl members being inalignment with each other and operable in the plane of said ratchetwheel to engage the same for alternatively driving the same, meanspivoting one of said pawl members to one of said bars for bodilymovement therewith and engaging said ratchet wheel for moving the samein one direction, means pivoting the other of said pawl members to theother of said bars for bodily movement therewith 3 and engaging saidratchet wheel for moving the same in said one direction, whereby saidratchet wheel is uni-directionally driven, a power takeoff shaft, a;spur pinion on said power take-off shaft and meshing with said drivingspur gear.
